Some items in World of Warcraft can become soulbound to one particular character, making it impossible to trade them or sell them to other players. There are two types: those that will bind when first equipped or used, and those that will bind when they are looted or picked up. When looting, you will get a warning dialog telling you that looting the item will permanently bind it to you when you either equip or loot such an item. Once an item is bound to you, it will indicate in the tooltip that it is soulbound just below the name of the item. You can sell soulbound items to vendor NPCs, but not to other players. Destroying these items, selling them to a vendor, or disenchanting them (if you are an enchanter) are the only ways of getting rid of these objects; you cannot mail them, trade them, or sell them in the auction house.

Acquiring Items

By mail from other characters or your own characters (that are on the same server).

Mail with an item in it takes 1 hour to arrive.

Mail with just a message and/or money arrives instantly.

Making them yourself

Tradeskills provide items that are one notch above equal-level quest items. However, you can send items you make to your other character (and to other players) or sell them to vendors or auction them at the auction house.
